SPECIFICATION forming part of Letters Patent No. 324,151, dated August 11, 1885.

Application tiled March 28, i885.

.To all whom t may concern:

Be it known that I, BRUNO E. PANZIG, a subject of the King of SaXony, residing in the city and county ot' Philadelphia, State of Pennsylvania, have-invented a new and useful Improvement in Cocks, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 represents a central vertical section of a cock embodying my invention. Fig. 2 represents a section at a right angle to Fig. 1. Fig. 3 represents a section in line m Fig. l. Figs. 4 and 5 represent sections of a inodiiication. Fig. 6 represents a section in line y y, Fig. 4.

Similar letters of reference indicate correA sponding parts in the several iigures.

My invention consists of a cock adapted for by-pass and other purposes, and possesses advantages, as will be hereinafter fully set forth.

Referring to the drawings, A represents the shell of a cock; and B represents a rotary valve therein, said valve being hollow and having ports C C in its side. Within the valve B is a valve, D, of semi-cylindrical form, both valves having one end passed through the shell, the valve B having a lever, E, and the valve D having athumb-piece, F, both for operating purposes. In the bottom oi' the shell is ijtted a screw, G, `which is adapted to be moved to and from the bottom edge of the valve B, said edge thus constituting a seat for the point of the screw.

The operation is as follows: The screw G is adjusted relatively to the amount of gas it is desired to pass through the cock through the ports O C'. When the port C is in communication with the cock, a small quantity oi' gas will iiow through the cock, so that a gas-burner may be kept constantly burning with 'a small light. Zhen a full light is required, the valve Bis turned so that the port C is in communicationv with the cock, as shown in Figs. 1, 2, and 8, and thus the gas ows through said port C. In this case the port C is closed by the said wall ofthe seat of the valve B. When. the port C is in communication with the valve, the port C will be closed (No model by the solid wall of the seat of the valveon the side opposite to that shown closing the port C.

Should it be desired to cut oit the entire flow of gas, the valve D is rotated, its motion being independent of that of the valve B,and it then covers the port C', it also being evident that the screw G may be employed for cutting off the entire iiow of gas.

In order to open and close the ports in the proper direction and limit the degree of rotation of the valve B, the side oi the latter is filed away, forming a shoulder, H, and toward the same projects ascrew, J, which is secured to the shell A, and acts as a stop to the walls of said shoulder. (See dotted lines, Fig. 3.) In Fig. 4 the screw J is shown entering a recess in the valve B for limiting the rotation of the latter, and an additional screw, J', is employed for limiting the inward or downward motion of the valve, the latter being accomplished in the construction shown in Figs. 1 and 3 by the screw J.

The cock is serviceable for water and other fluids.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A Icock for fluids having an outer valve provided with different-sized ports and an inner valve adapted to close the ports of the outer valve, devices for limiting the motion of said valve, and a screw whose point has a seat on the end of the outer valve serving to adjust or regulate the iiow of the iiuid, said parts being arranged, combined, and operated substantially as described.

2. A cock for Huids having the casing A, rotary valve B, provided with ports C and C', of different sizes, inner valve, D, handle E, thumb-piece F, screws J and J, and a screw, G, whose point is located adjacent to the bottom of the valve B as a seat, substantially as described.
